Each one of us has a set of significant relationships with particular individuals: persons with whom we share friendships or romantic partnerships; long-term projects to which we are devoted; communities to which we belong; ideals to which subscribe; artworks we love; and places we treasure. What's more, these relationships are personal; we each have such relationships with different sets of individuals. The central theme of my research is the nature and significance of these relationships in a number of ethical domains—including the moral, the aesthetic, and the social and political. More details on my research are available here.
